IMPROVEMENT IN MACHINES FOR MAKING CARPET-LININGS AND SIMILAR FABRICS.

Specification forming part of Letters Patent No. 222,037, dated November 25, 1879 5 application led October 13, 1879.

To all whom it may concern.-

Be it known that I, JOHN C. GRAY, of Providence, in the State of Rhode Island, have invented a new and nseful Machine for Making Oarpet-Linin gs and Similar Fabrics; and I do hereby declare that the following specification, taken in wconnection with the drawings making a part of the same, is a full, clear, and exact description thereof.

Figure l is a side elevation of my machine.

Fig. 2 isI a top view of the same. Fig. 3 is a with a thick brittle paper, which not only adds very much to its weight, but 'easily becomes broken and torn, after which the batting cannot be handled without injury, and

soon becomes worthless.

In my invention, Figs. l and 2, A is a roll of cotton-lap; B and B', rolls ot' cloth or netting; O, an endless apron; and D D', rolls for spreading the netting, all supported by a suit-able frame,`E. F and F' are lpairs of sizingrolls, and G and G' friction-rolls, all upon a frame, H. I is a drying-chamber, provided `with a fan, J, and steam-pipes K. L is a pair of compressing-rolls. L' Lz L3 are frictionrolls, and M M' M2 M3 are heated calendering or ironing rolls. N N' are measuring-rolls; N2, a friction-roll, and O a roll to receive the completed goods.

Motion being. imparted to the apron and the different rolls by suitable belts and gears, which it is not 'deemed necessary to particularly describe, the operation of my invention is as follows: V

The lap is unrolled from the roller A-and deposited upon the endless apron C, which carries it forward, and at the same time the cloth or netting is unrolled from the rolls B B', covering both the upper and lower side of the cotton. The cotton thus covered is now carried to and through the sizing-rolls F F', which size the cloth or netting upon both sides of the cotton, the lower roller ot' each pair being partly immersed in a trough or box of size, and rotating therein, all in a manner well understood. The batting, with its sized covering, is now carried back and forth through the dry- .ing-chamber I, which is provided with a fan, J, and steam-pipes K, by the aid of the rolls L', G', and L?, and delivered to the calendering or ironing rolls M M' M2 M3, which, being heated, remove any dampness remaining in the goods, and give to the cloth or netting a proper linish. Beforeleavingthedryingchamber l the batting passes through rolls L, which compress the edges, so that it can be lapped without increasing the thickness. The goods are now finished, and may pass to and be taken upon the roller O, unless it is desired to measure them, when they pass under the roll L, through the measuring-rolls N N', and under the roll N2 to the receiving-roll O.

The measuring-rolls N N', Figs.y l and 3, consist of a thirty-six-inch roll and a frictionroll, respectively, the latter of small diameter, to prevent the sheet from slipping over the roll N when it is disconnected from the re.- ceiving-roll O.

The roll N is provided upon its circumference with a block, P, to which coloring-matter is transferred from the box Q through the medium of a collar, B, uponthe rotating shat't S, and marks the cloth at each rotation of the roll N, or one for every yard.

What I claim as my invention, and desire to secure by Letters Patent, is

l. The endless apron O, for receiving and carrying the material, in combination with the sizing-rolls F F', the drying-chamber I, and the calendering or ironing rolls M M' M2 M3, the whole constructed and operating together substantially as described, for the purposes specited.

2. The measuring device consisting of the roll N, with its block l?, in combination with the collar and shaft B S and box Q, the whole constructed and operating substantially as described.

J. C. GRAY.
